Hyperbranched poly(aryl ether ketone)s(HPETFDEK-F) were synthesized from the combination of 3,3′,5,5′,-tetramethyl biphenyl-4,4′-diol(A_2) and B_3,a novel monomer 1,3,5-tris[4-(4-flourobenzoyl)phenoxy] benzene synthesized in our lab.

Hydroxyl-terminated(HPEEK-OH) and fluoro-terminated(HPEEK-F) hyperbranched poly(ether ether ketone) were prepared from the mixture of hydroquinone(A_2) and 1,3,5-tris[4-(4-fluorobenzoyl)phenoxy]benzene(B_3) with different A_2/B_3 mass ratios.

Fluorin-terminated hyperbranched poly(ether ether ketone)(HPDEEK-F) was synthesized via A 2+B 3 reaction.

The sulfonated polyaryletherketoneketone(S PEKK) was synthesized from cross linked polyaryletherketoneketone with 20% fuming sulfuric acid, and then it was used as catalyst in esterification of fumaric acid and methyl alcohol.

The sulfonated polyaryletherketoneketone(S-PKKK) was synthesized from cross-linking polyaryletherketoneketone with 20% fuming sulphuric acid, and then it was use as catalyst in esterification of phenylacetic acid and β-phenethyl alcohol.

The sulfonated polyaryletherketoneketone was synthesized by reaction of crosslinking polyaryletherketoneketone with 20% fuming sulphuric acid as sulfonating agent and used to catalyze the reaction of malic anhydride with 2ethylhexyl alcohol.

Through lots of trial experiments, our research team found a new approach to separate sPPESK which-we call precipitation separation method.
